TPS Question

[speedhop]

The m30 tps has a round 6 pin, the m20 has a 3 pin rectangular plug. How have you tackled this wiring challenge?

Searching this section has been very helpful. If your car is a manual, you want to use the manual E30 tps.

Yeah, no.

I tried the m20 one and the 3 switch pin doesn't mount correctly...the mounting pin is off. It's like a pie that has the wrong part missing. The word is not coming to me right now ha

Ah, then I'll be watching this to see how you resolve it. Sorry I can't be more help.....

Are you using a B35? You will probably need the TPS from a manual E34 or E32 if you are, OR just swap the throttle body from a B34. I have an extra throttle body with a bad TPS if you need one.

Cool, thanks for the help! I'll try and find a tps from a manual...I've got to go to the yard anyways.

Here's a link. That's for a 91 E34.

Thanks guys, another bit of info to file away.

Is there any way you can just use the auto TPS? Mine has the 6 pin plug also.

Is the only way to change it is to get a manual harness and TPS?

I didn't know that the round was auto plug and the manual had a different plug. So what I was going to do was use the original plug and solder the six wires into the the three from the m20 harness. I was under the impression that there are two sets of three, so scrapping one of each of the wires would work. Don't take my word for it. Try it out and let us know how it turns out.
